DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is predicated upon the provision of a membersuitable for providing sealing, baffling, reinforcement or a combinationthereof to one or more structures of an article of manufacture and aprocess for forming the member and applying the member to the one ormore structures of the article of manufacture. Together, the one or morestructures and the member form a system or assembly that is generallydesirable for the article of manufacture because of the functionalattributes (e.g., noise reduction, sealing, strength, combinationsthereof or the like) provided by the member. It is contemplated that themember may be employed in conjunction with a variety of structures ofvarious articles of manufacture such as boats, trains, buildings,appliances, homes, furniture or the like. It has been found, however,that the member is particularly suitable for application to structuresor assemblies of transportation vehicles such as automotive vehicles.Generally, it is contemplated that the member may be applied to variousstructures of an automotive vehicle such as components of a body, aframe, an engine, a hood, a trunk, a bumper, combinations thereof or thelike of an automotive vehicle.

The member typically includes one or more of the following:

-   -   i) a malleable carrier;    -   ii) an activatable material disposed upon the malleable carrier;        and    -   iii) optionally, one or more fasteners connected to the carrier,        the activatable material or both:

The process for forming the member typically include one or more of thefollowing steps:

-   -   i) providing a malleable carrier;    -   ii) associating an activatable material with the malleable        carrier;    -   iii) shaping of the activatable material, the malleable carrier        material or both; and    -   iv) optionally, connecting one or more fasteners to the        activatable material, the carrier or both.

As used herein, the term malleable as it applies to a carrier generallymeans that the carrier has a degree of pliability that allows thecarrier to be shaped or formed. A material that is malleable accordingto the present invention typically has a yield stress less than about1000 MPa but may be greater, more typically less than about a 700 MPa,more typically less than about 500 MPa and even more typically less thanabout 350 MPa, but typically greater than about 10 MPa but may be less,more typically greater than about 70 MPa, even more typically greaterthan about 100 MPa and still more typically greater than about 250 MPa.

Suitable malleable carrier materials can include, without limitation,polymeric materials (e.g., elastomers, plastics or the like), metals,composite materials, fibrous materials, combinations thereof or thelike. Materials including or composed substantially entirely of one ormore metals are particularly suitable for use as carrier materials.Exemplary metals include, without limitation, aluminum, steel, iron,magnesium, zinc, lead, tin, titanium, molybdenum, vanadium, zirconium,chromium, copper, tungsten, nickel, silver, gold, platinum, combinationsthereof or the like.

Generally, a malleable carrier may be formed in a variety ofconfigurations. In one embodiment, the carrier will be formed of one ormore strips of malleable material. As used herein, a strip of materialis any configuration of material having an extension length and amaximum diameter wherein the maximum diameter is substantially less thanthe extension length. For example, the maximum diameter should be lessthan 20%, more typically less than 10% and even more typically less than2% and even more typically less than 0.5% of the extension length. Theextension length is a length of a strip when the strip is arranged in asubstantially straight line and the maximum diameter is a maximumdimension of the strip substantially perpendicular to the length. Thus,for example, a coiled cylindrical wire could be considered a strip ifthe wire is uncoiled, arranged in a substantially straight line and themaximum diameter of the wire is substantially less than the extensionlength. Exemplary strips includes wires, coils, straps, combinationsthereof or the like.

Referring to FIGS. 1-3, there are illustrated examples of suitablecarrier materials 10, 12 and 14 suitable for use in the presentinvention. Each of the materials includes a plurality (e.g., 2, 3, 4, 5or more) of strips 18 intertwined (e.g., interwoven) with each other toform the materials 10, 12 and 14. In FIG. 1, the carrier material 10includes a plurality of interwoven strips 18 (e.g., wires). The carriermaterial 12 of FIG. 2 includes a plurality of strips 18 (e.g., wires)configured into a honeycomb arrangement. Moreover, the carrier material14 of FIG. 3 includes a plurality of strips 18 (e.g., wires) arranged toform relatively large openings 20 and relatively small openings 22.Generally, wire mesh and particularly metal or plastic wire meshproducts may be employed as carrier materials,

For forming a member according to the present invention, an activatablematerial is typically associated with (e.g., connected to, dispose upon,surrounding or the like) the carrier material. The carrier material maybe formed into a carrier before or after the activated material isassociated with the carrier material. For example, carrier material maybe cut to form a carrier of desired shape and the activatable materialmay be associated with the carrier thereafter. Alternatively,activatable material may be associated with the carrier materialfollowed by cutting or otherwise forming the carrier material to for thecarrier.

As used for the present invention, the term activatable material isintended to mean a material that can be activated to cure (e.g.thermoset), expand (e.g., foam), soften, flow or a combination thereofupon exposure to a condition. Thus, it is contemplated for the presentinvention that an activatable material may be activated to perform onlyone of aforementioned activities or any combination of theaforementioned activities unless otherwise stated.

A variety of activatable materials may be used for the member of thepresent invention. In one embodiment, the activated material may beformed of a heat activated material and may flow, cure (e.g.,thermoset), expand (e.g., foam) or a combination thereof upon exposureto heat. The activatable material may be generally dry to the touch andsubstantially non-tacky or may be tacky and, in either situation, may beshaped in any form of desired pattern, placement, or thickness, and mayhave substantially uniform thickness or variable thickness. Exemplaryexpandable materials include L-7102 and L-7220 foams available throughL&L Products, Inc. of Romeo, Mich. Another exemplary expandable materialis disclosed in U.S. patent application titled “Expandable Material”,Ser. No. 10/867,835,filed on Jun. 15, 2004 and incorporated herein byreference for all purposes.

Though other heat-activated materials are possible, a preferred heatactivated material is an expandable polymer or plastic, and preferablyone that is foamable. Particularly preferred materials are foamable orsealing materials, which include or are based upon an EPDM, an elastomeran epoxy resin, an acrylate or an acetate combinations thereof or thelike, which may be structural, sealing, baffling, acoustic or acombination thereof. For example, and without limitation, the foam maybe an epoxy-based material, including an ethylene copolymer orterpolymer that may possess an alpha-olefin. As a copolymer orterpolymer, the polymer is composed of two or three different monomers,i.e., small molecules with high chemical reactivity that are capable oflinking up with similar molecules.

A number of sealing, baffling or acoustic foams are known in the art andmay be employed in the present invention. A typical foam includes apolymeric base material, such as an epoxy resin or ethylene-basedpolymer (e.g. EMA, EVA or the like) which, when compounded withappropriate ingredients (typically a blowing and curing agent), expandsand cures in a reliable and predicable manner upon the application ofheat or the occurrence of a particular ambient condition. From achemical standpoint for a thermally-activated material, the foam isusually initially processed as a flowable thermoplastic and/or athermosettable material. Typically, the material will cross-link (e.g.thermoset) upon curing, which makes the material incapable of furtherflow.

One advantage of the preferred foamable or activatable materials overprior art materials is that the preferred materials can be processed inseveral ways. The preferred materials can be processed by injectionmolding, extrusion, compression molding or with a mini-applicator. Thisenables the formation and creation of part designs that exceed thecapability of most prior art parts.

While preferred materials have been disclosed, other materials may beused as well, particularly materials that are heat-activated orotherwise activated by an ambient condition (e.g. moisture, pressure,time, chemical reaction or the like) and cure in a predictable andreliable manner under appropriate conditions for the selectedapplication. Of course, the material may also be formed of non-curablematerials, non-expandable materials or otherwise. Thus, upon activation,the material may soften, cure and expand; soften and cure only; cureonly; soften only; or may be non-activatable.

One example of an expandable material is the epoxy based resin materialdisclosed in U.S. Pat. No. 6,131,897, the teachings of which areincorporated herein by reference. Some other possible materials include,but are not limited to, polyolefin materials, copolymers and terpolymerswith at least one monomer type an alpha-olefin, phenol/formaldehydematerials, phenoxy materials, and polyurethane materials with high glasstransition temperatures. See also, U.S. Pat. Nos. 5,766,719; 5,755,486;5,575,526; and 5.932,680, (incorporated by reference). Polyurethanematerials including a blocked isocyanate may also be employed. Ingeneral, the desired characteristics of the material include high glasstransition temperature (typically greater than 70 degrees Celsius), andadhesion durability properties. In this manner, the material does notgenerally interfere with the materials systems employed by automobilemanufacturers.

Other exemplar expandable materials can include combinations of two ormore of the following: epoxy resin, polystyrene, styrenebutadiene-styrene (SBS) block copolymer, butadiene acrylo-nitrilerubber, amorphous silica, glass microspheres, azodicarbonamide, urea,dicyandiamide. Examples of such materials are sold under the tradenameSIKAELASTOMER, SIKAREINFORCER and SIKABAFFLE and are commerciallyavailable from the Sika Corporation, Madison Heights, Mich.

In applications where the material is a heat activated, thermallyexpanding material, an important consideration involved with theselection and formulation of the material comprising the foam is thetemperature at which a material reaction or expansion, and possiblycuring, will take place. Typically, the foam becomes reactive at higherprocessing temperatures, such as those encountered in an automobileassembly plant, when the foam is processed along with the automobilecomponents at elevated temperatures or at higher applied energy levels,e.g., during paint, primer or e-coat baking or curing steps. Whiletemperatures encountered in an automobile assembly operation may be inthe range of about 148.89° C. to 204.44° C. (about 300° F. to 400° F.),body and paint shop applications are commonly about 93.33° C. (about200° F.) or slightly higher. If needed, blowing agent activators can beincorporated into the composition to cause expansion at differenttemperatures outside the above ranges. Generally, suitable expandablefoams have a volumetric range of expansion ranging from approximately 0to over 1000 percent (e.g., volumetric expansion of greater than 50%,100%, 200% or 500% of the original unexpanded volume of the material).

The material or medium may be at least partially coated with an activepolymer having damping characteristics or other heat activated polymer,(e.g., a formable hot melt adhesive based polymer or an expandablestructural foam, examples of which include olefinic polymers, vinylpolymers, thermoplastic rubber-containing polymers, epoxies, urethanesor the like) placed along the mold through the use of baffle technology;a die-cast application according to teachings that are well known in theart; pumpable application systems which could include the use of abaffle and bladder system, and sprayable applications.

Formation

Generally, formation of the member of the present invention can beaccomplished using multiple different techniques such an extrusion,molding (e.g., compression molding, injection molding, blow molding orthe like), machining, combinations thereof or the like. Such formationgenerally includes associating one or more masses of activatablematerial with the carrier and/or carrier material. The activatablematerial can be connected or attached directly or indirectly to thecarrier. Typically, however, the activatable material is disposed about(i.e., surrounds) a substantial portion of the carrier. In such anembodiment, it is typically desirable of the activatable material tosurround at least 30%, but possibly less, more typically at least 50%and even more typically at least 80% and still more typically at least90 or even 100 percent of the carrier,

According to one preferred embodiment, the activatable material isinjection molded about the carrier. In such embodiment, a carriermaterial is formed (e.g., cut) to a desired shape and/or size forforming the carrier. The carrier is then placed in a mold of aninjection molding machine and the mold is closed about the carrier.Activatable material is injected into the mold in a substantially fluidstate and allowed to substantially surround and adhere to the carrier.Then the member including the carrier and the activatable material areremoved from the mold.

In FIGS. 4 and 5, there is illustrated a member 30 that can be formedusing injection molding. For forming the member 30, a carrier 32 is cutfrom carrier material into a rectangular shape. The carrier 32 is thenplaced in a mold of an injection molding machine and the mold is closed.If the carrier 32 does not include a bend 34 as shown in FIG. 5, oncecut, the bend may be preformed prior to insertion of the carrier 32 inthe mold or the bend 34 may be formed upon closing of the mold.Thereafter, activatable material 38 is injected into the mold about thecarrier at an elevated temperature (e.g., a temperature that istypically greater than 30°, 40°, 60°, 80°, or even 100° C. but typicallyless than 220°, 170°, 120°, 100°, or even 70° C.) that maintains theactivatable material 38 in a relatively fluid state but does notsubstantially activate the material 38. The activatable material is thenallowed to cool such that it adheres to the carrier 32 thereby formingthe member 30.

According to one preferred embodiment, the activatable material isextruded or co-extruded about the carrier or carrier material. In suchembodiment, a carrier material is preferably fed to an extrusion diealong with activatable material that is exiting an extruder therebyforming a composite extrudate. In this manner, activatable material cansubstantially surround the carrier material. Thereafter, the extrudateincluding the carrier material, the activatable material or both can becut to a desired shape or configuration to form a member such as themember 30 shown in FIG. 5. Preferably, although not required, theactivatable material 38 is extruded at an elevated temperature (e.g., atemperature that is typically greater than 30°, 40°, 60°, 80°, or even100° C. but typically less than 220°, 170°, 120°, 100°, or even 70° C.)that maintains the activatable material 38 in a relatively fluid orviscoelastic state but does not substantially activate the material 38.Then, upon cooling, the activatable material can cool such that itadheres to the carrier 32 thereby forming the member 30.

Advantageously, formation of members using these techniques can providethe member with relatively complex or simple shapes and/or contours asneeded or desired. Moreover, the carriers of the members assist themembers in maintaining these shapes and particularly assist theactivatable material in maintaining its shape.

In any of the embodiments of the present invention, but particularly insituations where the carrier serves primarily to support the activatablematerial, it is preferable for the volume of the activatable material tobe substantially greater than the volume of the carrier. For example,the volume of the activatable material can be at least 200%, moretypically at least 500% and even more typically at least 800% the volumeof the carrier. As an exemplary calculation, 200% of a volume of 10 m³is 20 m³.

It is additionally contemplated that a member according to the presentinvention can include one or more fasteners such as adhesive, mechanicalfasteners magnets or the like for assisting in assembly the member to astructure of an article of manufacture (e.g., an automotive vehicle).Such fasteners may be integrally formed (e.g., molded) of the samematerial as the carrier, the activatable material or both.Alternatively, the one or more fasteners may be formed and separatelyattached to the member. As one examples a portion of the activatablematerial may be injection molded to extend outwardly from the membersuch that the portion may be interference fit into an opening of astructure of an article of manufacture. Alternatively, a portion of thecarrier may extend outwardly from the member and be attachable in thesame manner. As still another alternative, a separate fastener such astwo-side tape, a magnet or a push-pin or other mechanical fastener maybe attached to the member and then the fastener can be attached (e.g.,adhered, magnetized or interference fit) to a structure of an article.

Application

A member according to the present invention may be applied to a varietyof locations upon various structures a variety of articles ofmanufacture. Generally, a member in accordance with the presentinvention is quite suitable for application to a structure defining aninternal cavity. In such a circumstance, the member can be placed withinthe cavity and the activatable material of the member can be activated,upon exposure to a condition such as heat (e.g., in an e-coat, primer orpaint bake oven), to expand and/or adhere to walls of the structuredefining the cavity for providing baffling, sealing or reinforcement tothe structure.

The member of the present invention has been found particularly suitablefor application to structures of automotive vehicles. As can be seen inFIG. 6, there is illustrated a structure 44 (e.g., a pillar) of anautomotive vehicle wherein the structure 44 includes walls 46 definingan internal cavity 48. For exemplary purposes, the shape of the member30 of FIG. 5 is such that it contours correspond to the shape of thecavity 48 of the structure 44 of FIG. 6. Thus, the member 30 can beplaced in the cavity 48 with a relatively small clearance (e.g., lessthan 2.5 cm, more typically less than 1.0 cm and even more typicallyless than 0.4 cm and still more typically less than 0.2 cm) between theouter periphery of the member and that walls 46 defining the cavity 48.Of course, the member may also be substantially smaller than the cavity.

After placement of the member 30 in the cavity 48, the activatablematerial is activated to expand (e.g., foam), cure (thermoset) andadhere to the walls 46 of the structure 44. If the member 30 is designedto provide baffling, sealing and/or noise reduction to the structure 44,the activatable material will typically expand to a volume that is atleast 500%, although possibly less, more typically at least 800% andeven more typically at least 1400% its original unexpanded volume suchthat the member and particularly the activated material (e.g., foam)substantially entirely span a cross-section of the cavity 48. If themember is designed for reinforcement, the activatable material willtypically expand to a volume at least 5%, although possibly not at all,but typically less than 600%, more typically less than 400% and evenmore typically less than 250% its original unexpanded volume. Of course,the member could provide a combination of baffling, sealing andreinforcement to the structure such that it does any combination of theaforementioned. Moreover, the member could include two or more differentactivatable materials to assists in providing a combination of theaforementioned functional attributes.

Alternative Embodiments

FIGS. 7 and 8 illustrate a different embodiment of a member 50 accordingto the present invention. It will be understood that the features of themember 50 of FIGS. 7 and 8 can be employed in addition to or asalternatives to the previously described embodiments and the features ofthe previous embodiment can be employed with the member 50 of FIGS. 7and 8. The member 50 of FIGS. 7 and 8 includes a malleable carrier 52,activatable material 54 disposed about and substantially surrounding thecarrier 52 and, optionally, one or more fasteners 58.

The malleable carrier 52 can be provided as an elongated strip having aplurality of widened portions 60 with a plurality (e.g., 2, 3 or more)of openings 62 (e.g. through-holes) extending into and or through thecarrier 52. The carrier 52 can be formed of any of the materialsdiscussed herein as suitable malleable carriers.

The fasteners 58 are illustrated as mechanical fasteners and moreparticularly push-pins. The fasteners 58 can be attached to (e.g.,adhered to, interferingly fit with) the carrier 52, the activatablematerial or both. In the embodiment shown, the fasteners 58 areinterferingly fit to the carrier 52 by extending an elongated portion 64of each of the fasteners 58 respectively through the openings 62 of thecarrier.

The activatable material 54 can be any of the activatable materialsdiscussed herein and can be injection molded, extruded or otherwiseshaped about and/or applied to the carrier 52. Preferably, although notrequired, the activatable material is shaped about the carrier 52 and atleast a portion of the one or more fasteners 58 as in the illustratedembodiment.

The member 50 may be applied to a structure of an article of manufactureaccording to a variety of techniques. As one example, the fasteners 58of the member 50 may be interference fit into openings (e.g., throughholes) of a structure of an automotive vehicle (e.g., a pillar such asthat illustrated in FIG. 6) such that the activatable material islocated in a cavity of the structure. As an alternative, the fasteners58 may be interference fit into openings of a secondary carrier and thesecondary carrier along with the member 50 may be placed in a cavity ofa structure.

Advantageously, the malleable carrier 52 allows the member to be shaped(e.g., bent or curved) during application to accommodate contours of astructure or a secondary carrier thereby allowing the member to be moreeasily attached thereto. As shown in FIG. 8A, the member 50 is appliedto a contoured or curved substrate 66 (e.g., a structure or secondarycarrier) and the member 50 is curved or contoured to accommodate thecurved or contoured surface of the substrate 66. Preferably, afterlocation within a cavity, the activatable material can be activated aspreviously described to provide reinforcement, baffling or sealing tothe structure.

FIGS. 9 and 10 illustrate a different embodiment of a member 80according to the present invention. It will be understood that thefeatures of the member 80 of FIGS. 9 and 10 can be employed in additionto or as alternatives to the previously described embodiments and thefeatures of the previous embodiment can be employed with the member 80of FIGS. 9 and 10. The member 80 of includes a malleable carrier 82,activatable material 84 disposed upon and or about the carrier 82 and,optionally, one or more fasteners 88. 90.

The malleable carrier 82 can be provided as a frame (shown asrectangular) formed of an elongated strip. The carrier 82 can be formedof any of the materials discussed herein as suitable malleable carriers.

The fasteners 88, 90 are illustrated as mechanical fasteners and moreparticularly as tabs, which are preferably bendable and are integrallyformed of the same material as the carrier 82. As shown, a firstfastener 88 extends from one side of the carrier 82 and a secondfastener 90 extends from an opposite side of the carrier 82. The firstfastener 88 is generally hook-shaped.

The activatable material 84 can be any of the activatable materialsdiscussed herein and can be manually, automatically or otherwise appliedto the carrier 82. If the activatable material 84 is tacky, it may bedesirable to cover one or more surface of the material with releasepaper that can be removed from the material just prior to application ofthe member 80 to a structure. In the illustrated embodiment, theactivatable material 84 has a shape (e.g., rectangular) correspondinggenerally to the shape of the carrier 82 and the material 84 is adheredto at least one surface 94 of the carrier 82.

The member 80 may be applied to a structure of an article of manufactureaccording to a variety of techniques. In FIG. 11, the member is appliedto a pillar structure 98 of a vehicle. As shown, the pillar structure 98includes a first member 100 shown as a body side inner, a second member102 shown as a body side reinforcement and a third member 104 shown as abody side outer. The member 80 is attached to the second member 102 ofthe structure 98 by extending the first fastener 88 through an openingin the member 102 and hooking the first fastener 84 onto an edge of thesecond member 102. Thereafter, the second fastener 90 is bent around andhooked onto an edge at a distal end of the second member 102 by bendingthe second fastener 90 about the edge for at least temporarily fasteningthe member 80 to the structure 98 and particularly the second member102.

Preferably, after location within a cavity, the activatable material canbe activated as previously described to provide reinforcement, bafflingor sealing to the structure. In the particular embodiment illustrated,the member 80 is activated within a cavity 110 defined between the firstmember 100 and the third member 104 and the activatable material can beactivated to, not only provide reinforcement (e.g., against buckling) tothe structure 98, but also to provide a relatively strong reinforcedconnection between two reinforcements such as the second member 102 anda lower reinforcement 112 for the structure 98.

Unless stated otherwise, dimensions and geometries of the variousstructures depicted herein are not intended to be restrictive of theinvention, and other dimensions or geometries are possible. Pluralstructural components can be provided by a single integrated structure.Alternatively, a single integrated structure might be divided intoseparate plural components. In addition, while a feature of the presentinvention may have been described in the context of only one of theillustrated embodiments, such feature may be combined with one or moreother features of other embodiments, for any given application. It willalso be appreciated from the above that the fabrication of the uniquestructures herein and the operation thereof also constitute methods inaccordance with the present invention.
